Not in the PowerCLI cmdlets afaik.
You could try with the regular PowerShell cmdlets to scan a subnet and try to find ESXi nodes.
Wouldn't it be easier to use AutoDeploy and the PowerCLI cmdlets for that?
With the Script bundles you can configure your ESXi node after installation.
See William's Custom script bundle is now possible with Auto Deploy in vSphere 6.5
